BUFFING-WHEEL.

SPECIFICATION forming part of Letters Patent No. 291,709, dated January8, 1884.

Application filed September 26, 1883. (N model.)

To all whom, it may concern:

Be it known that I, HERBERT E. FOWLER, of New Haven, in the State ofConnecticut, have invented a new and useful Improvement inBuffing-\Vheels, of which the following is a full, clear, and exactdescription.

In the manufacture of buffing-wheels the fibrous portion for thereception of the polishing-powder is usually made by cutting circu- 1Olar disks of cloth or other fiber, each disk having a central hole forthe mandrel of the wheel. These disks are put upon said mandrel untilthe desired thickness is obtained, and the end blocks and bolts are thensecured in place, and

the wheel is complete. In these disks of cloth the threads of the warpand woof cross one another at right angles, as in all ordinary cloth,and in use the wheels made of these disks will fray out on four sides,the threads of the warp 2 and woof separating and rendering the diskirregular. This unevenness of the Wheel is a great detriment,necessitating trimming the wheel or discarding it altogether.

The object of my invention is to produce a 2 5 continuous circularfabric for buffing-wheels, wherein the weft-threads all radiate from thecenter and the warp-threads follow the circular form of the fabric. Theadvantage of such a fabric is that both edges have a selvage, and

0 in a buffing-wheel made of such a fabric the ends of all theweft-threads are presented on the periphery of the wheel, and in usethis buffing-wheel will wear evenly and accomplish superior work. 4

In the drawings, Figure 1 is an elevation of a buffing-wheel. Fig. 2 isa perspective View of a piece of the continuous fabric, and Fig. 3

is a plan of a piece of the fabric.

The buffing-wheel is, as usual, composed of 40 a mandrel, a, endblocks 1) b and clampingnuts 0 c to secure the intermediate fabric, d.

My improved fabric (1 is to take the place of the usual disks of cloth.It is Woven in a continuous form, with one edge so much shorter than theother that it assumes a spiral form 5 with an opening in the center, thethreads of the warp following the circular form of fabric and thethreads of the weft standing radially. The weaving is preferablyperformed in a J acquard loom, in a manner similar to the weaving of agore in a corset, so that the fabric is composed of trapezoidalsections, as illustrated in Fig. 3, some of the weft-threads passing allacross and others only partially across, so that the weft-threads at theextreme portions of the section converge to a point which corresponds tothe axis of the buffingwheel.

In making a wheel from this fabric a section is cut off of the properlength to produce the desired thickness of wheel and laid in coilsaround the mandrel, forming a disk or wheel of numerous layers, andthese are clamped together or secured in the usual manner.

A buffing-wheel made with such a fabric will wear evenly, the ends ofthe weft-threads being exposed upon the whole peripheral surface of theWheel, and such buffing-wheel will of necessity be more durable anduniform in its operation than the wheels heretofore made.

I claim as my invention 1. In combination with a mandrel and theclamping ends of a buffing-wheel, a fabric for the same having one edgelonger than the other, so as to be coiled as a fiat spiral around themandrel, the threads of the warp following a circular direction, and thethreads of the weft crossing the same in radial lines from the center oraxis, substantially as set forth.

2. A fabric for buffingwheels having one edge longer than the other, soas to be adapted So to being coiled up into a flat circular form ofnumerous layers, substantially as set forth.

Signed by me this 21st day of September,

HERBERT E. FOWLER.
